lFlags
Flags that indicate the data to be shown and the plotting scale. You can use a bit-wise OR (|) to specify one flag from each group.
The following flags represent the data to be shown:
|
Value |
Meaning |
|
DSP_FT_MAG |
[0x0001] Plot harmonics magnitude data. |
|
DSP_FT_PHS |
[0x0002] Plot harmonics phase data. |
The following flags represent the plotting scale. These are ignored when DSP_FT_PHS is set:
|
Value |
Meaning |
|
DSP_FT_NORM |
[0x0010] Plot harmonics magnitudes using the normal linear scale. |
|
DSP_FT_LOG |
[0x0020] Plot harmonics magnitudes using logarithmic scale. |
